Therefore, it increases daily the demand of the quality of the image.

Conventional optical systems of portable electronic devices usually adopt four lenses or five lenses structure as main structure. However, since the pixel of the portable electronic devices continuously raises, and more end-users are demanding for cameras having large aperture, which is equipped with functionalities such as low light mode or night mode. The conventional optical image capturing systems may not be satisfied to meet those advanced photography requirements.

Therefore, it is an important issue about how to effectively increase the amount of light admitted into the optical image capturing system and further elevate the image quality thereof.

The length of the outline curve of any surface of single lens within the range of maximum effective half diameter affects the capability for correcting the surface aberration and the optical path difference between the rays in each field of view. Longer outline curve length may lead to a better capability for aberration correction, but the difficulty of production may simultaneously become higher as well. Hence, the length of the outline curve of any surface of single lens within the range of the maximum effective half diameter has to be controlled, and especially, the proportional relationship (ARS/TP) between the length of the outline curve (ARS) of the surface within the range of the maximum effective half diameter and the central thickness (TP) of the lens to which the surface belongs on the optical axis has to be controlled. For example, the length of the maximum effective half diameter outline curve of the object-side surface of the first lens is denoted as ARS11, and the central thickness of the first lens on the optical axis is TP1, wherein the ratio between both of them is ARS11/TP1. The length of the maximum effective half diameter outline curve of the image-side surface of the first lens is denoted as ARS12, and the ratio between the ARS12 and TP1 is ARS12/TP1. The length of the maximum effective half diameter outline curve of the object-side surface of the second lens is denoted as ARS21, and the central thickness of the second lens on the optical axis is TP2, wherein the ratio between both of them is ARS21/TP2. The length of the maximum effective half diameter outline curve of the image-side surface of the second lens is denoted as ARS22, wherein the ratio between ARS22 and TP2 is ARS22/TP2. The proportional relationships between the lengths of the maximum effective half diameter outline curve of any surface of the other lenses and the central thicknesses (TP) of the other lenses to which the surfaces belong on the optical axis are denoted according to the regular pattern shown above.

The outline curve length within a range of ½ entrance pupil diameter height (HEP) of any surface of single lens specifically affects the capability for correcting the aberration in the shared region of each field of view on the surface and the capability for correcting the optical path difference among each field of view. Longer outline curve length may lead to a better capability for aberration correction, but the difficulty in production of such lens may simultaneously become higher as well. Hence, the outline curve length within a range of ½ entrance pupil diameter height (HEP) of any surface of single lens has to be controlled, and especially, the proportional relationship between the outline curve length within a range of ½ entrance pupil diameter height (HEP) of any surface of single lens and the central thickness (TP) on the optical axis has to be controlled. For example, the outline curve length of the ½ entrance pupil diameter height (HEP) of the object-side surface of the first lens is denoted as ARE11, and the central thickness of the first lens on the optical axis is TP1, wherein the ratio thereof is ARE11/TP1. The outline curve length of the ½ entrance pupil diameter height (HEP) of the image-side surface of the first lens is denoted as ARE12, wherein the ratio of the ARE12 to TP1 is ARE12/TP1. The outline curve length of the ½ entrance pupil diameter height (HEP) of the object-side surface of the second lens is denoted as ARE21, and the central thickness of the second lens on the optical axis is TP2, wherein the ratio thereof is ARE21/TP2. The outline curve length of the ½ entrance pupil diameter height (HEP) of the image-side surface of the second lens is denoted as ARE22, wherein the ratio of the ARE22 to TP2 is ARE22/TP2. The proportional relationships of outline curve lengths of the ½ entrance pupil diameter height (HEP) on any surface of the other lenses of the optical image capturing system to the central thicknesses (TP) on the optical axis of the other lenses to which the surfaces belong are denoted according to the regular pattern shown above.

The height of optical system (HOS) may be reduced to achieve the minimization of the optical image capturing system when the absolute value of f1 is larger than f6 (|f1|>|f6|).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| meet the aforementioned conditions, at least one lens among the second lens to the fifth lens may have a weak positive refractive power or a weak negative refractive power. The weak refractive power indicates that an absolute value of the focal length of a specific lens is greater than 10. When at least one lens among the second lens to the fifth in the optical image capturing system has the weak positive refractive power, the positive refractive power of the first lens can be shared by it, such that the unnecessary aberration will not appear too early. On the contrary, when at least one lens among the second lens to the fifth lens has the weak negative refractive power, the aberration of the optical image capturing system can be slightly corrected.

Besides, the sixth lens may have negative refractive power, and the image-side surface thereof may be a concave surface. With this configuration, the back focal length of the optical image capturing system may be shortened to keep the optical image capturing system minimized. Moreover, at least one surface of the sixth lens may possess at least one inflection point, which is capable of effectively reducing the incident angle of the off-axis rays, thereby further correcting the off-axis aberration.

In the optical image capturing system provided by the present invention, the lens may be made of glass or plastic material. If the lens is made of the plastic material, it can reduce the cost of manufacturing as well as the weight of the lens effectively. If lens is made of glass, it can control the heat effect and increase the design space of the configuration of the lens with refractive powers in the optical image capturing system. Besides, the object-side surface and the image-side surface of the first lens through sixth lens may be aspheric, which can gain more control variables and even reduce the number of the used lens in contrast to traditional glass lens in addition to the use of reducing the aberration. Thus, the total height of the optical image capturing system can be reduced effectively.

Furthermore, in the optical image capturing system provided by the present disclosure, when the surface of lens is a convex surface, the surface of that lens is basically a convex surface in the vicinity of the optical axis. When the surface of lens is a concave surface, the surface of that lens is basically a concave surface in the vicinity of the optical axis.

Thereby, the optical image capturing system can expand the application aspect.

The optical image capturing system of the present invention can further include a driving module based on the demand. The driving module may be coupled with the lens and enable the movement of the lens. The foregoing driving module may be the voice coil motor (VCM) which is applied to move the lens to focus, or may be the optical image stabilization (OIS) which is applied to reduce the frequency which lead to the out focus due to the vibration of the camera lens in the process of the photographing.

In the optical image capturing system of the present invention, at least one lens among the first lens, second lens, third lens, fourth lens, fifth lens and sixth lens may further be a light filtering element for light with wavelength of less than 500 nm based on the design requirements. The light filtering element may be achieved by coating film on at least one surface of that lens with certain filtering function, or forming that lens with material that can filter light with short wavelength.

The image plane of the optical image capturing system of the present invention may be a plane or a curved surface based on the design requirement. When the image plane is a curved surface (e.g. a spherical surface with curvature radius), it is helpful to decrease the required incident angle that make the rays focus on the image plane. In addition to the aid of the miniaturization of the length of the optical image capturing system (TTL), it is helpful to elevate the relative illumination at the same time.

Fourth Embodiment

Please refer to FIG. 4A and FIG. 4B, wherein FIG. 4A is a schematic view of the optical image capturing system according to the fourth embodiment of the present invention and FIG. 4B shows the longitudinal spherical aberration curves, astigmatic field curves, and optical distortion curve of the optical image capturing system in the order from left to right according to the fourth embodiment of the present invention. FIG. 4C is a transverse aberration diagram of the longest operation wavelength and the shortest operation wavelength for tangential fan and sagittal fan, of which the longest operation wavelength and the shortest operation wavelength pass through an edge of aperture at the position of 0.7 field of view on the image plane, according to the fourth embodiment of the present disclosure. As shown in FIG. 4A, in the order from an object-side surface to an image-side surface, the optical image capturing system includes a first lens 410, a second lens 420, a third lens 430, an aperture 400, a fourth lens 440, a fifth lens 450, a sixth lens 460, an Infrared filter 480, an image plane 490, and an image sensing device 492.

The first lens 410 has negative refractive power and is made of glass material. The object-side surface 412 of the first lens 410 is a convex surface and the image-side surface 414 of the first lens 410 is a concave surface.

The second lens 420 has negative refractive power and is made of glass material. The object-side surface 422 of the second lens 420 is a concave surface and the image-side surface 424 of the second lens 420 is a concave surface.

The third lens 430 has positive refractive power and is made of glass material. The object-side surface 432 of the third lens 430 is a convex surface and the image-side surface 434 of the third lens 430 is a convex surface, and both the object-side surface 432 and the image-side surface 434 are aspheric.

The fourth lens 440 has positive refractive power and is made of plastic material. The object-side surface 442 of the fourth lens 440 is a convex surface and the image-side surface 444 of the fourth lens 440 is a convex surface, and both the object-side surface 442 and the image-side surface 444 are aspheric. The object-side surface 442 has one inflection point.

The fifth lens 450 has negative refractive power and is made of plastic material. The object-side surface 452 of the fifth lens 450 is a convex surface and the image-side surface 454 of the fifth lens 450 is a concave surface, and both the object-side surface 452 and the image-side surface 454 are aspheric. The object-side surface 452 has one inflection point.

The object-side surface 462 of the sixth lens 460 is a convex surface and the image-side surface 464 of the sixth lens 460 is a convex surface, and both the object-side surface 462 and the image-side surface 464 are aspheric. Wherein the image-side surface 464 has one inflection point. Hereby, the configuration is beneficial to shorten the back focal distance of the optical image capturing system so as to keep its miniaturization. Besides, it can reduce the incident angle of the off-axis rays effectively, and thereby further correcting the off-axis aberration.

The infrared filter 480 is made of glass material and is disposed between the sixth lens 460 and the image plane 490. The infrared filter 480 does not affect the focal length of the optical image capturing system.

Eighth Embodiment

Please refer to FIG. 8A and FIG. 8B, wherein FIG. 8A is a schematic view of the optical image capturing system according to the eighth embodiment of the present invention and FIG. 8B shows the longitudinal spherical aberration curves, astigmatic field curves, and optical distortion curve of the optical image capturing system in the order from left to right according to the eighth embodiment of the present invention. FIG. 8C is a transverse aberration diagram of the longest operation wavelength and the shortest operation wavelength for tangential fan and sagittal fan, of which the longest operation wavelength and the shortest operation wavelength pass through an edge of aperture at the position of 0.7 field of view on the image plane, according to the eighth embodiment of the present disclosure. As shown in FIG. 8A, in the order from an object-side surface to an image-side surface, the optical image capturing system includes an aperture 800, a first lens 810, a second lens 820, a third lens 830, a fourth lens 840, a fifth lens 850, a sixth lens 860, an Infrared filter 880, an image plane 890, and an image sensing device 892.

The first lens 810 has positive refractive power and is made of plastic material. The object-side surface 812 of the first lens 810 is a convex surface and the image-side surface 814 of the first lens 810 is a concave surface. Both the object-side surface 812 and the image-side surface 814 are aspheric. The image-side surface 814 has one inflection point.

The second lens 820 has negative refractive power and is made of plastic material. The object-side surface 822 of the second lens 820 is a concave surface and the image-side surface 824 of the second lens 820 is a concave surface, and both the object-side surface 822 and the image-side surface 824 are aspheric. The image-side surface 824 of the second lens 820 has two inflection points.

The third lens 830 has negative refractive power and is made of plastic material. The object-side surface 832 of the third lens 830 is a convex surface and the image-side surface 834 of the third lens 830 is a concave surface. Both the object-side surface 832 and the image-side surface 834 are aspheric. Each of the object-side surface 832 and the image-side surface 834 has one inflection point.

The fourth lens 840 has positive refractive power and is made of plastic material. The object-side surface 842 of the fourth lens 840 is a concave surface and the image-side surface 844 of the fourth lens 840 is a convex surface, and both the object-side surface 842 and the image-side surface 844 are aspheric.

The sixth lens 860 has negative refractive power and is made of plastic material. The object-side surface 862 of the sixth lens 860 is a concave surface and the image-side surface 864 of the sixth lens 860 is a concave surface. The object-side surface 862 has two inflection points and the image-side surface 864 has one inflection point. Hereby, the configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep its miniaturization. Besides, the incident angle of the off-axis rays can be reduced effectively, and thereby further correcting the off-axis aberration.

The infrared filter 880 is made of glass material and is disposed between the sixth lens 860 and the image plane 890. The infrared filter 880 does not affect the focal length of the optical image capturing system.

In the eighth embodiment of the optical image capturing system, a sum of the focal lengths of all lenses with positive refractive power is denoted as ΣPP, and the conditions as follows are satisfied: ΣPP=12.785 mm and f5/ΣPP=0.10. Hereby, it is helpful to appropriately distribute the positive refractive power of a single lens to other lenses with positive refractive power, so as to restrain occurrences of significant aberration during the transmission of incident light.

In the eighth embodiment of the optical image capturing system, a sum of the focal lengths of all lenses with negative refractive power is denoted as ΣNP, and the conditions as follows are satisfied: ΣNP=−112.117 mm and f6/ΣNP=0.009. Hereby, it is helpful to appropriately distribute the negative refractive power of the sixth lens to other lenses with negative refractive power.
